The -generation of shared DSA parameters is described in -L<DSA_generate_parameters(3)|DSA_generate_parameters(3)>; -L<DSA_generate_key(3)|DSA_generate_key(3)> describes how to -generate a signature key. Signature generation and verification are -described in L<DSA_sign(3)|DSA_sign(3)>. - -The B<DSA> structure consists of several BIGNUM components. - - struct - { - BIGNUM *p; // prime number (public) - BIGNUM *q; // 160-bit subprime, q | p-1 (public) - BIGNUM *g; // generator of subgroup (public) - BIGNUM *priv_key; // private key x - BIGNUM *pub_key; // public key y = g^x - // ... - } - DSA; - -In public keys, B<priv_key> is NULL. - -Note that DSA keys may use non-standard B<DSA_METHOD> implementations, -either directly or by the use of B<ENGINE> modules. In some cases (eg. an -ENGINE providing support for hardware-embedded keys), these BIGNUM values -will not be used by the implementation or may be used for alternative data -storage. For this reason, applications should generally avoid using DSA -structure elements directly and instead use API functions to query or -modify keys. - -=head1 CONFORMING TO - -US Federal Information Processing Standard FIPS 186 (Digital Signature -Standard, DSS), ANSI X9.30 - -=head1 SEE ALSO - -L<bn(3)|bn(3)>, L<dh(3)|dh(3)>, L<err(3)|err(3)>, L<rand(3)|rand(3)>, -L<rsa(3)|rsa(3)>, L<sha(3)|sha(3)>, L<engine(3)|engine(3)>, -L<DSA_new(3)|DSA_new(3)>, -L<DSA_size(3)|DSA_size(3)>, -L<DSA_generate_parameters(3)|DSA_generate_parameters(3)>, -L<DSA_dup_DH(3)|DSA_dup_DH(3)>, -L<DSA_generate_key(3)|DSA_generate_key(3)>, -L<DSA_sign(3)|DSA_sign(3)>, L<DSA_set_method(3)|DSA_set_method(3)>, -L<DSA_get_ex_new_index(3)|DSA_get_ex_new_index(3)>, -L<RSA_print(3)|RSA_print(3)> - -=cut |
